Abstract

As a continuation of a previous paper [Biopolymers 16, (1977)], in which we described a general method for the evaluation of the diffusion constants of a rigid macromolecule with an arbitrary configuration, this paper presents a theory for evaluating the relaxational behavior of the molecule in solution. The diffusion equation of a molecule subjected to hydrodynamic or electric forces is solved and both a complex viscosity and a complex dielectric constant are obtained by assuming that the molecule is composed of Tokes spheres and, in the dielectric property, the molecule possesses a fixed charge distribution. The viscoelasticity of a rigid rod is calculated and compared with the analytical results.
